Airtac MDD Multi-position Double Rod Cylinder MDD32X20
The AirTAC Airtac MDD Multi-position Double Rod Cylinder MDD32X20 is a genuine MD multi-mount cylinder (double rod), 32 mm bore. Its compact square body fixes from six directions and mounts side by side to save space. It delivers about 402.1 N of push force at 0.5 MPa. A bumper cushions the impact.

About the Airtac MDD Multi-position Double Rod Cylinder MDD32X20
The MDD32X20 is a 32 mm bore, 20 mm stroke multi-mount cylinder with rods on both sides. With rods reducing the effective area on each face, theoretical thrust at 0.5 MPa is 345.6 N per rod side. The compact square body fixes from 6 directions - front, back, left, right, top and bottom - so cylinders mount side by side to save space, with magnetic-switch slots around the body and high guide precision (no added lubricant). Operating pressure is 0.15-1.0 MPa (22-145 psi), medium is air filtered to 40 um, speed is 30-500 mm/s, and cushioning is a bumper.
This is a genuine AirTAC part from the MD family: a standard double-rod variant, not the no-rotating MK version. As the SKU shows, this model carries no magnet. The port is 1/8" with PT thread. Dimensions and side-load limits vary with stroke, so we confirm exact figures from the AirTAC datasheet on request.

Specifications follow the official AirTAC MD/MK multi-mount data. The front cover and piston are short, so avoid an over-long stroke. An optional high-temperature seal material extends the range to 0 to 150 C. Overall dimensions vary per stroke and allowable side-load is published as curves — ask us and we confirm from the datasheet.
How to choose
The 32 mm bore is the largest multi-mount size, giving 345.6 N theoretical thrust per rod side at 0.5 MPa - pick it when clamping or pressing forces are highest. The double-rod MD layout puts a rod on both faces for dual-sided or symmetric actuation; if rod rotation must be prevented, choose the MK family instead. The 20 mm stroke stays well inside the bore 32 table (up to 60 mm), but keep strokes short given the compact cover. Magnet versions add the S suffix, and thread can be PT (this model) or G.
Applications
Small-parts clamping
Clamp small workpieces in a machining or assembly fixture, using both rods to drive opposing clamp pads from one compact body.
Gate and stopper duty
Actuate a stopper or diverter gate on a conveyor, fixed to the top or side of the frame where space is too tight for a tie-rod cylinder.
Side-by-side indexing
Line up several 32 mm bodies side by side in a narrow station to push parts between fixture positions at each cycle.
FAQ
Should I choose the MDD32X20 double rod or a standard MD cylinder for this bore?
Choose the MDD32X20 when you need a rod on both faces - for example symmetric clamping or actuation from either side of the body. Because the rods reduce the piston area, theoretical thrust at 0.5 MPa is 345.6 N per rod side. A standard single-rod MD of the same bore pushes with 402.1 N at 0.5 MPa. If the rod must not rotate, move to the MK no-rotating family instead.
How do I mount this cylinder and where do I find exact dimensions?
The square body fixes from 6 directions - front, back, left, right, top and bottom - and units mount side by side to save space. Keep strokes short, since the cover is compact and an over-long stroke is not recommended. Overall dimensions and allowable side-load depend on stroke, so confirm the figures from the AirTAC datasheet.
